The '79 (and I think '80) engines don't have shutter valves, also the intake manifold on '79 (maybe '80 too) are different. I think I have heard the '79 manifold flows better. I think the carbs on the '79 are slightly different as far as location of the idle speed and mix screws. '79s also used a thermal reactor rather than exhaust manifold and a heat exchanger instead of catalytic converters. And trannys are different too, but thats not really the engine. Thats all I know of.
